I think reducing number of claims may have negative impact to website. I imagine that with longer timer between claims, traffic to website would significantly reduce.
And now I'm trying to imagine how many years it would take to reach 30k Satoshi treshold with 3 Satoshi/h rate

.
Tell me about it!
Now I just claim once daily since I can't really be bothered with its extremely slow earning rate since it pays like a few cents a
day. For almost a year, my balance hasn't attained the minimum threshold of $3.
But that's because I can't complete offer walls, surveys and the PTC ads just pay too little. :p
